The obligation on NGC to purchase CEC and/or TEC via a) or b) above will be included in the CUSC If NGC purchase CEC and/or TEC via a) the price will be negotiated bilaterally.  If NGC purchase CEC and/or TEC via method b) the price and methodology will be set down in the relevant charging methodology.
